This machine'consists essentially of a driving shaft 1 fixed in I two supports or upyrig'hts 2 providedou the framing 3 of the apparatus and it rec'ei esits motion from a loose The hub of this pulley 4 is }71OVidt3d W1ti1 a cam 6' fittingagainst a second cam 7 fixed pulley l mounted on'a fixed shaft 1 and 1" show front elevation' v Fig. 4 is a section on the'li ne ATB 'of Fig. 1, and

on the end of the" shaft 5. The arrangement v is such that when the pulley rotates in the direction ofifthe arrow (Fig. 1) the cams 6 and 7 are moved apart so as to produce a lateral movement of the pulley onthe shaft 5 toward'the interior of the machine in the manner of a claw clutci.

ends the cam on the hub of the pulley falls back into the notch formed behind the fixed 'cam in consequence ofthe pressure exerted upon the said hub by a spring 8" provided on. the shaft 5 between the pulley and the When thesetwo cams have moved beyond their projecting the'right hand. with teeth on apart of the inner surface of .its rimand' whenithas terminated its move ment toward the left. it engages by means of this toothed POlilOli t) with a pinion 10 fixed on the driving shaft 1- in such a manner as to impartintermittent rotary motion to this shaft. v v

()n a si-otted bench 1T1 formed as a slide- --way. there are bolted two puppet bearings 13 carrying spindles14. 15 fol producing the deslredtwists in'the heddles that are ided with heads 16-. 17 for forming the end This pulley 4 is pro 'ided eyelets and they are rotated by thedri ing shaft 1 through the medium of tootliml wheels 18 mounted on thisshaft. and of toothed P1111011 gearing 19.20 arranged in The.

a similar manner in both puppets. head 16 comprises a matrix-21 of the shape which itis, desired to give to the end eyelets and capable of' being embedded into the said head in such a' manner as to fit in the recess 22. By means of a small red 23 fixed von thisdnatrix sliding in. the lower' part of the head IG and pro ided with a spring arranged between 'tlie projection of the head and thebody of the matrix 21.'the latter is returned into its normal po,- 1 sition (Fig.1), This matrix 21 has a s'mal-I "vertical slit' 26 of suflicient width to receivethe end of'the metal wire employed in the manufacture of the heddles. This small yertical slit is arranged preferably diagonally in. the body of the matrix 21' and ends in a small horizontal notch 97 so that when the matrix is inserted into the head 16. .the metal wire introduced into the .slit and engaged in this notch 27 will be-cut by slrearmg. The slit 26 in the matrlx 21 may also be pa rallel to the major axis of this matrix asindlcated 1n Flg. 5. In thls case. the end of the wire .will be passed around a small rod 21? adapted to slide in an extension of the head 16 and beheld on the latter by a small spring. This rod is raised slightly for the purpose of passing the end of the metal 5 wire below its head 21.

. For the purpose of cutting the end of thewire. the matrix 21 is normally inserted by hand and returned into its initial position by a sprin 24.- In the case of metal wires 'of considerablethickness this matrix may framing of the apparatu. This approach however be inserted if necessary by means.

7e beingmanufactured. Thesesnindlesare'proof a lever arranged in a suitable manner below an extension of the head 16, and having its shorter arm connected to the lower end of the niatrix die. The head 17 of the other spindle 15. is likewise provided with amatrix die having the same shape as the die 21. This die 28 is also capable of being lowered in order to occupy the recess'29 provided for this purpose and it is returned into its initial position by a spring 30 mounted onthe small sliding rod die between the body of the latter and the short arm 3'2. At the outer end of the two spindles 14. 15 there is mounted on anextension of these latter, a stop 33 provided with aset screw iii. A coiled spring 35 is arranged on each of these outer extensions oi" the spindles between the stops 33 and the body of each puppet. These springs 35 exert a certain pressure against thebodyof the puppet through the medium of a washer 30 and a set of balls maintained in place by a ring 37; Each spindle isthusable to yield to a certain extent to a pull exerted upon it toward the center of the bench 11. but it is prevented from moving back beyond a certain limit by the action'of a shoulder 3% formed on the forward part of each spindle which carries the head for making the eyelets.

The two puppets 12, 13 with their spindles and heads for making the end eyelets are fixed on the bench llby means of tight.- ening screws 39 in such a manner that they can be shifted in accordance with the length which the heddles are to have. The toothed wheels 13 can therefore be shifted and they are likewise provided for this purpose with tightening screws in their hubs.

On. the bench it there is also arranged between the two puppets a support in) constituting a bearing which maintains a toothed pinion 42 between its upr 'hts .1. This pinion i2 is cut away at a pmrtion of its circun'iference in such a manner as to form a gap 43 (Fig. 2) corresponding to a similar gap ii; provided in the tops of the two uprights ll. The said pinion it more over contains in the bottom of the trap 43 a tongue or matrix die 45 serving for the formation of the eye of the heddle, the shape of this eye being determined by the shape of the said tongue. The pinion i2 is rotated by the toothed wheel 46 mounted on the The support 40- for the toothed pinion if, as also the puppets at the ends of the bench. are fastened to the said bench by a screw provided with a nut.

On each side of the pinion 42 there is arranged a blade or part 47 mounted on a vertical rod 48 adapt d to be raised and lowered in the socket if) pro led with a driving shaft 1.

\ertical slit 3 wherein the part i? an be engaged in its downward movement. Each uttsocket it has a small base plate and a fixing 31 of the ing rods 70 which are screw provided with a nut 51 whereby the sockets can be fixed on the bench 11 and can be shifted when necessary. The small rods 48 that carry the parts 47 are connected by links 52 to a horizontal bar 53 arranged below the bench 1.1. Near the puppet'13 there is provided on the bench 11 a socket 54 which is likewise fixed to the bench by means of a screw and a nut. This socket 5% is traversed by a small rod 55 which carries at its upper end a tongue 56 and is connected at its lower end by a ring'57 to the liar 53. Another socket 58 is arranged on the said bench 11 near the puppet 12. This socket is also fixed to the bench by means of a screw and nut. Inside the socket 58 there is arranged a small rod 59 carrying at its upper end tongts 60 consisting of two small jaws one of which is preferably slightly'shorter than the other in order to facilitate the introduction thereinto of the end of the, wire used in. the manufacture of the heddle. The shorter jaw of the tongs is formed inside with a horizontal notch by which the end of the wire held in. the hand is sheared whenthe tongs ()0 move down i'nto the interior of the socket For the purpose of avoiding a faulty shearing of the wire through play in the tongs (30, the tongs are surrounded with a split sleeve (30 upon which acts a set-screw 60" The lower end of the rod 59 provided with the said tongs is connected by a ring ()1 to thevhorizontal bar 53. The tongs (30 as, also the tongue 56 and the two parts 47 can be raised and lowered by means of the bar This bar 53 is connected to two bell-crank levers 62 which are capable of rocking in vertical planes on the axis 63 upon the horizontal cross bars 64 of the framing 3 of the apparatus (Figs. 2' and 3). A second bar or rod 65 is arranged moreover on the frame 3 and is held in the bearings 66 This bar 65 is provided at one end with a bell-crank at its other end with two small cranks (if).

to two small connectadapted to be moved forward and backward in guiding sleeves 71 hen the lever 7 is lowered the connecting rods are moved forward toward the bellcrank levers 62 and by engaging in a notch '72 provided on the angle of each bell-crank lever the latter levers are caused to oscillate downward thereby producing a descending movement of the bar 53 and the parts connected therewith. The small tongs 60. the parts 47. and the tongue it) are moved down by this downward movement and caused to enter into their sockets. On raising the lever 7 and thus witlnlrawlng" the connecting rods 70 from the notches T2. the bar 53 is raised again by the spring 7 that connect the lower arms of the. levers (32 to the bearings 74. ()n thus rising again, the bar 53,

which connect said bar the tongs 60, the parts 47 and the tongue 56 which are fixed at one end to the sleeves 71 and at their other end to a ring provided on each 1 connecting rod 70 facilitate the advance of to rock downward and'thus move the the latter rodsv toward the bell-crank le vers 62. In the operation of the machine the lowermg of the bar 53 and of the parts 60, 17 and 56 fixed upon the latter, is produced by means of c'ams 76 mounted on the driving shaft 1' and provided with a projection 77 which is adapted to strike rollers 78 mounted on the ends of the upper arms of the levers 62. These levers are thereby caused bar 53 in the said direction. The rise of this bar 53 is produced by means of a projection 79 which is provided on the pulley 4 and which strikes at a suitable moment against the roller 68 provided on the end of the lever 67. On the end of the driving shaft 1 opposite to the end where the driving pulley engages, there is keyed a cam 80 having a lateral projection 81 (Fig. 1) ending in a second cam 82.

()n the lateral projection 81 of the cam 80 there is mounted loose another cam 83 which is maintained in its position of rest by a pawl 84 having the form of a bell-crank lever (Fig. 4) adapted to pivot on an axis 85 on the framing of the apparatus and kept in engagement in a notch 86 of the cam 83 by means of a coil spring 87. A counter pawl 88 provided on the cam 30 allows of disengaging the retaining pawl 8% from its notch and thus liberating the cam 83 when the fixed cam 80 is rotated in the opposite direction to that of the hands of a watch.

The loose cam 83 has. a slot 89 provided with a tightening nut 90 which can be shifted if necessary. A notch provided in the fixed cam 80 allows of shifting the nut 90 and forms an abutment 91 against which the nut 90 is made to strike at a given moment. A fourth cam 93 is mounted loose on the end of the driving shaft 1 and is connected by a 'chain provided with a coiled spring 9% to the framing of the apparatus. This fourth cam 93 has a pawl 95 bearing against the cam 82 and adapted to engage at the proper moment in a notch 96 formed in the cam 82.

On rotating the driving shaft in the opposite direction to that of the hands of a watch the retaining pawl 84 is first dlsengaged from the loose cam 83. The fixed cam 80 continues to rotate and then carries with it the cam 83 in consequence of the nut 90 being made to bear against the stop notch 91. The cam 82 continues to rotate since it is formed in one piece with the fixed cam 80, and this cam 82 in encoun tering with its notch 96 at a glven moment the pawl 95 provided on the fourth cam 93, carries the latter around with it and thus produces a strong tension of the spring 94. This rotation of the cams S0, S2. 83, and 93 is continued until the re; taining pawl 84 engages again 'in the notch of the cam 83 and thus arrests th'l atter. This momsnt ,corresponds to tlfe unclutching of tlfe al riving pulley. The rotation of the cams which has caused the tensioning of the spring 91 is thus stopped and the cam 93 which is always in engagement with the cam,82 and consequently also with the cam is returned to therear bythe actionof the spring 94. Since the cams 80 and 82 are fixed on the driving shaft they impart to the latter and its gear wheels a return motion which is arrested bya tappet 97 fixed on the fixed cam 80 when it, ar-

rives at the end of the slot 89 of the loose cam 83 that is held at that moment by the pawl 84. The rotation of these cams and the driving shaft 2 in the reverse direction will be so much the longer as the driving of the loose cam 83 shall have been retarded and the nut 90 ,shall have been placed farther in the slot 89 with reference to the stop 91 of the/cam 80. At this moment, the parts are in the position they occupied at thebeginning and they are ready for a fresh operation. The driving pulley 4 will havecontinued to rotate in the meantime and will again come into engagement with the pinion 10 on' the driving shaft in such a manner as to produce a. fresh forward rotation of the latter which is followed by a.-

rotation in thereverse direction and so on' as herembefore described.

If necessary.

when for any reason the operator desires to retard the restarting of the machine the pulley 4 can be maintained as desired in the declutched position by means of an auxiliary de-clutching device preferably at the foot of the machine. At the end of each rotation in the reverse direction the pawl 95 of the cam 93 is disengaged from the cam 82 by means of a lever 92 which is mounted on the rear bar 65 and is actuated at the same time as the lever (37 by means of the projection 79 provided on the drivingpulle a The operation of the entire apparatus and the formation of the metal heddles are as follows: The steel or iron wire employed in the manufacture of the heddles after having been cut to the desired length, is inserted with one end into the small slot 26 in the die 21 in the head 16 and is brought behind the tongs 6O, the parts 47, the tongue 56,

around the second die 28in the head 17, in

, 15with their heads 16,

' pose on the ended apart of its cams and thus produces by means of the toothed wheels 18, 46 and the pinions 19, 20, rotation of the spindles 14, 17 for forming the end eyelets on the one hand, and rotation of the central pinion 12 on the other hand. By this means a first twist is imparted to the double wire stretched between the two heads 16, 17. In this first twisting, the eye is formed by the rotation of the tongue or die 45 in the central pinion 42, the twisting necessary for the formation of this eye being determined by the two parts 47 which are engaged between the two lengths of wire. On the other hand the two end eyelets are formed in this first twisting operation and the latter is limited for this pur- 56 and on the side of the head 16 by the tongs 60, these two parts 56 and GObeing likewise engaged for this purpose between the two lengths of wire. This first twisting with formation of the eye and the two end eyelets is'terminated at the moment when. the stops T7 of the cam 76 provided on the driving shaft 1 strike the rollers 73 of the bell-crank levers a2 and by rocking the lattercause a downward movement of the bar 53. This bar 53 carries down with it the tongue 56, the parts 17 and the tongs 60 and causes them to enter into their guiding sleeves. The tongs 60 in descending into its socket 58 cut off, flush with the heddle that is being formed, the end of the steel wire which is held in the hand.

Thefirst stage of the operation being it is now necessary to twist the two lengths of wire of the leash throughout the extent comprised between the eye and the two end eyelets. The spindles ll. 15 and consequently the heads 1G, 17 which hold the end eyelets of the heddle, thus continue to turn and thereby produce in the two halves of the heddle the desired twist until the driving pulley disengages with its toothed sector from the pinion 10 of the driving shaft 1 and pushed back into its initial position by the spring 8. As soon as this pulley has become disconnected the hereinbefore described rearward movement or re verse rotation takes place which is produced by the spring 91. The heddle is thus subjected also to a rotation in the reverse di rection so as to produce what is known as the alineincnt of the heddle, that is to say for bringing the two end eyelets of the heddle in one and the same plane while the eye remains in a different plane. which may be at rigl'it angles or not at right angles to the lil'st plane. This operation ends the serond stage of the manufacture of the lied die and there now remains only to drive n the two dies '21. 2%. the former of which cuts by shearing the other end of the wire of'the heddle which is situated inside the side of the head 17 by the tongue loop in the slit 26 of the die 21. The lash is now completely finished and leaves the apparatus ready for insertion in the heddles or bars "of the heddle frames without requiring any further treatment by hand.

Two supports consisting of flat rods having the shape of the end eyelets of the hedand the tongue 56 to their operative posi-- tions 1) The apparatus is now ready to form another heddle. The devices which serve for the formation of the eye of the heddle may naturally vary as regards theirdimensions and their shapes and it is to be undeistood that any other suitable modifications may be made in the-construction of the hereinbefore described and illustrated apparatus without departing from the nature of the present invention.
